Application January 28, 1952, Serial No. 268,544

The present invention relates to new and useful improvements in memorandum attachments for use with telephones whereby a roll of memorandum paper is supported for feeding onto a platen or writing surface at the front of a telephone base. I

An important object of the invention is to provide a spring contracted extensible sub-base attachable under the base of a telephone and enclosing a roll of memorandum paper at the rear of the sub-base and from which the paper is fed under the telephone to a platen or writing surfaceat the front of the telephone.

Another object is to provide a novel paper feeding means enclosed in a hollow platen at the front of the telephone.

A further object is to provide adaptor units held in the extensible sub-base for use with round or ovate shaped bases of telephones and utilizing the spring means for holding the units in a contracted assembled position in clamping engagement with the telephone.

A still further object is to provide a device of this character of simple and practical construction, which is neat and attractive in appearance, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which: 7

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of my invention, the numeral 5 designates the telephone sub-base gen- 4 Claims. (Cl. 281-41) 2 erally and which includes a front platen or writing surface unit 6 and a rear paper roll supporting unit 1.

Rear unit I comprises a housing [0 rising at the rear end of a base plate ll. Housing I0 is formed with a loading opening l2 for placing a roll of paper I3 therein for mounting in bearings i i and i5 in the opposite sides of the housing. The free end of the paper passes through an opening it in the bottom of the housing to opposing guide channels H at the bottom of base plate ii to feed the paper forwardly underthe latter. The paper is held'in an elevated position above a supporting surface on which the device is placed by means of felt pads I8 secured to the underside of base plate H at the side edges of the latter.

The free end of the paper passes forwardly at the front end of base plate II to enter a horizontal opening I9 in the lower rear wall of a hollow body which forms the front platen or writing unit 6. An idler roller 21 is rotatably mounted in the front portions of body 20 and around which the paper passes to a front trans verse slot 22 in a sloping sunken top '23 of the body to feed the paper outwardly on top of the platen or writing unit 6 and rearwardly through a rear transverse slot 24 under a cutter 25 which projects rearwardly at the top of the platen unit. A transverse shaft 26 is rotatablymounted in the sides of body 26 and to which a pair of rubber or other suitable friction rollers or wheels 27 are secured in frictional engagement with the underside of the paper at its edge portions. A knurled operating wheel 28 is also secured to shaft 26 with the uppermost portion of the wheel exposed in an opening 29 in the top of body 20 for turning the wheel by the fingers of a person.

A pair of guide rods 36 project rearwardly from body 20 for sliding in bores 3| in the front ends of base plate I! and a coil spring 32 is connected to body 20 and base plate I! to contract the front and rear units 6 and 1 against the front and rear respectively of the base 33 of a telephone placed on base plate II and between the units. Cutter 25 overlies the front of telephone base 33 and a lip 34 is formed at the upper front portion of paper housing It) to overlie the rear of the telephone base.

A pair of arcuate adaptor units 35 and 36 of hollow construction are shaped to fit closely at the opposite sides of a round or ovate-shaped telephone 31 and are provided with dowels 38 which project from the front and rear ends of the adaptor units to slidably enter openings 39 lies the base of the telephone.

In the operation of the device, and when desiring toruse thesame 'with a conventionalsduare shaped telephone base; as shown in"- Figure 2', the front and rear units 6 and '7 are pulled outwardly in extended position and the telephone- 33 placed therebetween. Spring 32 contractsor pulls the units inwardly against the front and? rear sides of the telephone to hold the units tightly thereon.

After loading a roll of paper It in housing land feeding the free end of'the paper forwardly in guide channels I! under the base plate I land into front unit 6, the wheel 28 may be turned to feed;fresmportionsofLthei'paper on top of sloping platen- 23: for writing thereon.

When the attachment is to be used with.- round or ovaltelephone bases, .suchas shown in Figure 7 the adaptors St and. 36are placedbetvaeen the) frontvand. rear. units: 6: and: 7'- for embracing thebase-of. the telephone. at the sides'thereof.

In view of the;foregoingdesoriptiontaken in conjunction with the I accompanying drawings it is'believed. that a clearv understanding of the device will be. quite apparent to those skilled in-this. art. Almoredetaileddescription isaccordingly deemed unnecessary.

It; is to be understood, however, that even though there is". herein shown and described a preferred. embodiment of the invention-the same is susceptible to certain changes fully comprebended-by. the. spirit. of the-invention as herein described and the. scope of.-. the appended. claims.

Having described-my invention, what is-claimed as new is:
